A coducting circular loop of area 1mm^2 is placed coplanarly with a long, straight wire at a distance of 20 cm from if. The straight wire carries an electric current which changes from 10A to zero is 0.1 s. Find the average emf induced in the loop in 0.1 s.

A large circular loop of radius 1 metre has total resistance 4Omega . A variable current is folwing through the loop. The current at any instant is given by equation l = lA, where i is time in second.

A long wire carrying a steady current I lies in the plane of circular conducting loop placed at a certain distance from the wire. There will be an induced current in the loop if it is

Two different wire loops are concentric and lie in the same plane. The current in the outer loop (I) is clockwise and increases with time. The induced current in the inner loop
